Spiral Nails
The most tenacious of all nails in terms of holding power is the
spiral
nail
(also known as the
drive screw
). Its shank is spiral so that as the
nail is driven, it turns and grips the wood. Its main use is to secure
flooring, but it is also useful on rough carpentry.
Corrugated Fasteners
This fastener is a small section of corrugated metal with one sharp-
ened and one flat edge.
Corrugated fasteners
are often used for mak-
ing boxes or joining wood sections edge to edge (see Figure 1-11).
They come in a variety of sizes.
Staples
Many varieties of
staples
are available, from ones used to secure
cable and fencing to posts (such staples are always galvanized) to
ones used in the various staple guns. Fence staples range in size from

inches, and some are designed (the so-called
slash
point
)sothat the legs spread when the staple is driven in place. This
makes it grip better.
